WARNING: Always wear an ESD wrist strap grounded to the bench or frame when
working on electronic components.
Note: Fan filters can be removed from the chassis without turning off the power. A finger-safe
perforated panel separates the moving fans from the filters. TheT1100 AS chassis does not have
to be extended from the frame for this procedure.
1. Open the front fascia by unscrewing the knurled screws on either side of the chassis, and
unlocking the front fascia.
Then, carefully lower the front fascia. See
page 114. The rectangular and square fan filters are attached to the inside of the front fascia.
CAUTION: Be sure you do not unplug the cable from the printed circuit board
behind the front fascia while opening the front fascia. Removing this cable from
its connections will cause the server to shut down.

3. Insert the new filters into the metal retainers on the inside of the face plate.
Note: The wire mesh should be facing up when you insert the new filter and facing the inside
of the chassis when the front fascia is closed.
4. This procedure is complete.
